We recommend using Bio-lubricating oil or Bio-lubricating grease for “open” lubrication points or nipples (as specified in the operating instructions). We recommend using Bio-slushing oil to preserve machines and attachments (do not apply on painted covers). You can brush or spray the oil. Anti-corrosive agents are environmentally friendly and degrade fast. Using ecologically safe Bio-lubricants and Bio-anti-corrosives, you contribute to environmental protection and to the wellbeing of humans, animals and plants. Fuel This engine runs smoothly on commercial unleaded regular and supergrade petrol (including E10). 6 Do not add oil to petrol. If, for environmental reasons, you use unleaded petrol, make sure the fuel is drained completely when shutting down the engine for more than 30 days. This is to prevent resin residue from depositing in the carburetor, fuel filter, and tank. Or add a fuel stabilizer to the fuel. For further instructions refer to “Engine Preservation”. Maintenance and Repair: The trained mechanics of your agria workshop expertly carry out any maintenance and repair work. You should only carry out major maintenance work and repairs on your own, if you have the proper tools and knowledge of machines and internal combustion engines. Do not hammer against the flywheel with a hard object or metal tools as it might crack and shatter in operation, causing injuries and damage. Only use suitable tools to pull off the flywheel. agria Grassland Mower 5300 Instructions for Unpacking and Assembly Open the box top. l Cut the two rear corners open and fold down the box sides.

Safety Instructions Before starting the engine, read the operating instructions and note: 1 Warning This symbol marks all paragraphs which affect your safety. Pass all safety instructions to other users and operators. Due Use The grassland mower is constructed solely for the cutting of grass and similar plants as well as thin non-wooded scrub in land & forest management, green spaces, and other such areas and may also be used as a snow-clearing machine after it has been fitted with a suitable rake blade (due use). Any other type of operation is considered undue. The manufacturer is not liable for any damages resulting from undue use, for which the risk lies with the user alone. When the grassland mower is used on public roads, the local national road traffic rules must be observed, e.g. reflectors, lights. The grassland mower is not intended for use with a trailer on public roads or as as a tractive machine. General Instructions on Safety and Accident Prevention Basic Rule: The standard accident prevention regulations must be adhered to, as well as all other generally accepted rules governing operational safety, occupational health and road traffic regulations. For drives on public roads, the national traffic code applies. Accordingly, check the grassland mower for road and operational safety each time you take up operation. Only persons familiar with the mower and instructed on the hazards of operation are allowed to use, maintain and repair the mower. Teenagers of 16 years or younger may not operate the grassland mower! Only work in good light and visibility. Operator’s clothes should fit tight. Avoid wearing loose fitting clothes. Wear solid shoes. Note the warning and instruction signs on the mower for safe operation. Compliance is for your own safety. Due use includes compliance with manufacturer’s instructions on operation, maintenance and repair. When transporting the mower on vehicles or trailers outside the area to be mowed, ensure that the engine is turned off. Any unauthorized changes to the mower render manufacturer liability null and void. Careful with rotating tools – keep at a safe distance! 8 agria Grassland Mower 5300 1. Safety Instructions Beware of coasting tools. Before you start any maintenance or repair on them, wait until tools have come to a complete stop. Foreign powered parts shear and crush! Riding on the attachment during operation is not permitted. Implements and their weight affect the driving, steering, braking, and tip-over characteristics of the mower. Therefore, ensure steering and braking functions are sufficient. Match operating speed to conditions. Do not change settings of governor. High engine speed increases risk of accidents. Working Area and Danger Zone The user is liable to third parties working within the mower’s working range. Staying in danger zone is not permitted. Check the immediate surroundings of the mower before you start it. Watch out for children and animals. Before you start work, clear the area from any foreign object. During operation, always watch out for further objects and remove them in time. For operation in enclosed areas, ensure that a safety distance is kept to enclosures to prevent damage to tools. Operation and Safety Devices 1 Before you start the engine Become familiar with the devices and operating elements and their functions. Above all, learn how to turn the engine off quickly and safely in an emergency. Ensure that all protective devices are mounted and positioned to provide protection. With no implement mounted, make sure PTO-shaft is covered with the protective cap. Starting the engine Do not start engine in closed rooms. The carbon monoxide contained in the exhaust fume is extremely toxic when inhaled. Before you start the engine set all operating elements to neutral or idling position. For starting the engine, do not step in front of the mower and the implement. Operation Never leave the operator’s position at the steering handle while mower is at work. Never adjust the operating handles during work – danger! agria Grassland Mower 5300 9 1. Safety Instructions 1 During operation the operator must keep at a distance as defined by the steering handle, especially when turning the machine. Implements Riding on the implement during operation or in transport is not permitted. Always use appropriate tools and wear gloves when changing implements and parts thereof. If clogging occurs in the implement, turn off the engine and clean the implement with an appropriate tool. In case of damage to the grassland mower or to the implement, immediately turn off the engine and have it repaired. Only mount implements with the engine and PTO switched off. For mounting and dismounting implements bring support leg into proper position and ensure stability. Secure mower and implements against rolling off (parking brake, wheel chocks). If steering causes problems, immediately bring the mower to a halt and turn it off. Have the malfunction removed without delay. Beware of injuries while coupling implements. To prevent the mower from sliding on slopes, make sure it is secured by another person using a bar or a rope. This person must be located at a higher position than the vehicle and at a safe distance from the attachment at work. Secure mower and implement against unauthorized use and rolling off when you leave the machine. If necessary, install transport or security devices and secure. If possible, always work horizontally on the slope. Mowing Attachment End of Operation Never leave the mower unattended with the engine running. Before you leave the grassland mower, turn off the engine. Secure grassland mower against unauthorized use. If mower is equipped with ignition key, remove the key. For all other versions, remove spark plug connector. 10 Mount implements as specified and only couple at specified points. Handle with care! Sharp blades of the cutter bar may cause injuries! Remove knife guards only for mowing and refit immediately after work has finished. For transport and storage always mount the knife guards. Secure finger bars additionally with tension springs. Do not transport the dismounted cutter bar without knife guards. agria Grassland Mower 5300 1. Safety Instructions Before mounting and dismounting the cutter bar, make sure all blades are protected by the knife guard. Always wear safety gloves and use proper tools when exchanging cutting tools. To exchange the mowing knife and to mount/dismount the knife driver, make sure that you turn screws away from cutting edges. Do not carry out repairs like welding, grinding, drilling, etc. on structural and safety-relevant parts (e.g. coupling devices)! For grinding the mowing knives, always wear safety goggles and gloves. Keep mower and implement clean to avoid risk of fire. Weights Check nuts and screws regularly for tight fit and re-tighten, if necessary. Always fit weights onto appropriate weight mounting devices. Snow Clearing Ensure snow dozer is mounted correctly! Wear slip-proof shoes. When swivelling the snow dozer watch out for crush and shear points. Adjust working speed to conditions. Operator may be injured when the mache comes in contact with solid objects. Maintenance Never carry out any maintenance or cleaning with the engine running. After maintenance and cleaning, ensure that you re-install all safety and protective devices and adjust them properly. Only use original agria spare parts. All other commercial spare parts must correspond to quality and technical requirements specified by agria. Storage It is not allowed to store the mower in rooms with open heating. Never park the mower in closed rooms with fuel left in tank. Fuel vapours are hazardous. Before you work on the engine, always remove spark plug connector (petrol engine only). Check regularly and, if necessary, replace all protecting devices and tools subject to wear and tear. Replace damaged cutting tools. agria Grassland Mower 5300 11 1 1. Safety Instructions Engine, Fuel, and Oil 1 Never let the engine run in closed rooms. Extreme danger of intoxication! For the same reason, also replace damaged exhaust parts immediately. Caution with hot engine parts! The exhaust and other engine parts become very hot, if the engine runs and immediately after turning off. Hold for sufficient distance from hot surfaces and keep children away from the running engine. Be careful when dealing with fuel. Great danger of fire! Never refill fuel close to open fire, inflammable sparks or hot engine parts. Do not refill fuel in closed rooms. Do not smoke when refilling! Refill only with the engine switched off and cooled down. Do not spill any fuel, use a proper filling device. In case of fuel spillage, pull the grassland mower away from the spillage before you start the engine. Make sure fuel is of specified quality. ventilated places safe from spark formation or flames. If necessary, dispose of tins in hazardous waste deposits. Be careful when draining hot oil, danger of burns. Make sure oil is of specified quality. Storage is in approved cans only. Dispose of oil, greases, and filters seperately and properly. Tyres and Tyre Air Pressure When working on tyres, make sure grassland mower is parked properly and secured against rolling off. Any repairs are to be carried out by trained mechanics only and with the appropriate tools. Regularly check tyre air pressure. Excessive pressure may cause bursts. Use appropriate tyre air pressure when mounting weights or implements. Re-tighten attachment bolts of drivewheels or check tightness when doing maintenance work. Store fuel in approved cans only. For safety reasons the petrol tank and fuel cap should be replaced regularly. Store anti-corrosive agents and stabilizing liquids out of reach of children. If sickness and vomiting occur, see a doctor. If fuel has contacted eyes, rinse them thoroughly, avoid inhaling of vapours. Electrical System and Battery Persons having a pacemaker must not touch live parts of ignition system when the engine is running. Read and observe enclosed instructions. Before you dispose of opened and seemingly empty pressurised tins (e.g. of assist-starting liquids) make sure they are completely empty. Empty them in 12 agria Grassland Mower 5300 1.

Commissioning and Operation Commissioning the Machine Please note that durability and operational safety of the engine depend to a large extent on its breaking-in. Always allow a cold engine to warm up for some minutes and never run it at full throttle at the beginning. Please note: for the first 20 hours of operation (break-in period) do not use the engine at full power. Make sure you check and maintain air filters regularly and use clean fuel. Only use branded petrol. Only use fresh, clean fuel (not older than 3 months) and approved fuel cans to be purchased in special shops. Rusty sheet metal cans or fuel cans not suited for petrol are not permitted. For the first commissioning or after longer periods of no operation, fill fuel tank to maximum to avoid starting problems. Be careful when dealing with fuel. Fuel is easily inflammable and explosive in certain conditions! 4 l Do not refill in closed rooms. l Before each fuel fill, shut off the engine and wait until it has cooled off. l Never refill close to open fire, inflammable sparks or hot engine parts. l Do not smoke during filling! l Do not spill any fuel, use a proper filling device.

Cleaning Machine 55 èI After cleaning with air-compressed water jets immediately lubricate lubrication points on the machine and operate mowing drive for a short time to press out penetrated water. Apply grease generously to leave a grease neck around bearing to prevent water, plant sap and dirt from penetrating. Engine Clean engine only with a cloth. Avoid spraying with water jets, as water might penetrate into ignition and fuel system and cause malfunctions. agria Grassland Mower 5300 41 5 5. Maintenance d) Drive-wheels Storage For longer periods of no operation prepare the grassland mower for storage. Proceed as follows: a) Clean thoroughly Repair paint coat b) Spray all shining parts and cutter bar with Bio-slushing oil. c) Engine preservation l Drain the fuel completely from the system, see Petrol is an extremely inflammable and sometimes even explosive fuel. Do not smoke within the machine’s operating range and keep away fire and sparks. W Or fill fuel tank and add fuel stabilizer (agria No. 799 09). - Observe instructions. 5 Support drive-wheels in such a way that tyres have no ground contact. Pneumatic tyres are quickly destroyed, if left standing under load and un-inflated. e) Clutch Always park mower with hand clutch lever pulled (“0” – pawl locked in place). Otherwise, clutch problems may result due to corrosion. f) Storing the machine To avoid severe corrosion: - to preserve the machine from atmospheric influences Operate the engine for approx. 1 minute. Do not park the machine in: l Change the engine oil - humid rooms l Fill a tea-spoon of engine oil (approx. 0.03l) into the spark plug opening. Slowly crank the engine. - in rooms where fertilizer is stored l Reinstall the spark plug and pull the starter rope until you feel resistance. Pull a bit further. This closes the intake and outlet valves to improve the engine’s protection from internal corrosion. - in stables or adjacent rooms. g) Protect machine l Crank the engine slowly at 2–3 week intervals (spark plug connector is removed). 42 agria Grassland Mower 5300 with cloth or a similar cover. 5 5 agria Grassland Mower 5300 43 6.
